GmMMP1 protein interacting with soybean mosaic virus protein, gene of GmMMP1 protein, method for improving soybean resistance to soybean mosaic virus and application of GmMMP1 protein

The invention relates to the technical field of gene engineering, in particular to GmMMP1 protein interacting with soybean mosaic virus protein and a gene of the GmMMP1 protein, in particular to a method for improving resistance of soybeans to soybean mosaic viruses and application of the GmMMP1 protein, the GmMMP1 gene is cloned, a plant over-expression vector and a knockout vector are constructed, and transgenic soybeans are obtained by combining a soybean genetic transformation technology; the disease resistance phenotype of a plant proves that the soybean matrix metalloproteinase gene GmMMP1 can improve the disease resistance of soybeans to soybean mosaic viruses; the GmMMP1 is proved to be possibly interacted with 6K1 and HC-Pro proteins of the soybean mosaic virus in a yeast system; an important gene resource is provided for cultivating a new soybean variety with high soybean mosaic virus resistance through a molecular technical means, and the method has wide application potential for enhancing soybean
